University of Texas at Arlington researcher Yunyao Li has been selected by NASA to develop a system that gives communities early warning when wildfire smoke may make the air unsafe to breathe.
“Our project aims to enhance wildfire air quality forecasting capabilities and develop tools that advance decision-making processes related to wildfire air quality and health management,” said Dr. Li, assistant professor in UT Arlington’s Department of Earth and Environmental Sciences and co-principal investigator of the grant from NASA’s Science Mission Directorate Earth Science Division.
Wildfires are a major source of hazardous air pollution. Research shows that exposure to wildfire smoke can lead to long-term respiratory problems and even death—and the health risks aren’t confined to areas near the fire. Smoke can drift hundreds of miles, affecting communities far from the source. In June 2023, wildfires in Quebec caused severe air pollution as far away as New York City and Washington, D.C.
Large wildfires are becoming more frequent across the United States, exposing millions to unhealthy air. While air quality forecasting can reduce the harm caused by wildfire smoke, it remains a challenge due to unpredictable emission rates, shifting smoke patterns and changing weather conditions.

“Wildfires are becoming more and more of a threat in many parts of the U.S. and abroad, and accurate air quality forecasting is critical to protecting the health of people who might feel the effects of these fires far from their origin,” said Arne Winguth, professor and chair of the Department of Earth and Environmental Sciences. “This study will help provide valuable tools to enhance these forecasting capabilities.”
Li is working with co-investigators from New York University, the U.S. Naval Research Laboratory and Kaiser Permanente Northern California Division of Research, with additional collaborators from NASA, NOAA, the EPA and the U.S. Forest Service.

“This system will leverage Earth observations to develop a sophisticated model-weighting technique, thereby enhancing current air quality forecast capabilities,” Li said.
Next, the team will use the forecasting system to collaborate with key stakeholders in developing products and solutions that support informed decisions about air quality and public health.
Among the tangible benefits are a fire smoke visualization tool and patient-centric messaging system to improve real-time communication of air quality risks. The tool will also contribute forecasts to the EPA’s AirNow program, enhancing the agency’s ability to deliver accurate and timely information to the public.
